Summary: After my poor Xonar Essence STX (Btw, this is a high-end desktop sound card by Asus) died and feeling the need to find a replacement, i went on to purchase the Nuforce HD. I did my research. The reviews on-line were great. Suppose i can't go wrong...? The Nuforce HD is small (6" x 3.5" x 1") but feels solid. It requires an external power adapter. The one that comes with the unit is rated at 24 watt. The unit is well made with aluminum in silver and black.
Summary: I am using these along with my HD650 Sennheiser headphones. It should be noted that the HD650s are known for requiring a lot of power to be driven to their full potential. And since the NuFore Icon is doing a fantastic job with this, I can safely recommend this amp/dac to anyone for any use. Also, the difference between using the NuForce Icon versus the FiiO 9+7 (another amp/dac system) is extremely clear.
Summary: A few instant facts: 1. It use USB as the only input and it comes with an USB cable. 2. It has only got the 6.3mm headphone jack, but it comes with a 3.5mm adapter. 3. The only output apart from headphone jack is the RCA output -- and it's volume CAN be controlled by the nob! 4. The power cord comes with a universal converter so that it can be used WORLDWIDE. 5. It comes with a well made stand so that you can put the unit straignt up. I love its simplisity.
Summary: this Nuforce Icon HD is really a no brainer for dac/amp combo at the price range. plenty of power, not distorted, and noticeable improvement on both my AKG q701, ultrasone hfi780, and iem like turbine copper.
Summary: this item can help to improve the performance of your headphone. I used it with a AKG Q701.I meet some problem with the adapter, and sller sent me a new one.Generally speaking, this item worked well.
Summary: I got this for someone else, but had to take a listen first. The package lends itself to me getting into it and trying it without any visible signs of doing such, so let's get going with the review. I need to explain that I really only ever listen to music on my laptop with some good earphones (Shure) or headphones (AKG). I also use SRS HD Audio Lab on my laptop's output and it works very well.
Summary: NuForce Icon HD greatly improves the sound of my computer and AKG 701 headphones combination. If you are listening to a music service like Spotify Premium you do not need to by CDs anymore, since it is very difficult to notice that CD sound is only a little bit better than the Spotify Ogg Vorbis 320 kbps sound. If your favorite music is available only in your own CD, it takes only two minutes to copy it to your computer.
